Hello everyone. I have been roaming around these forums but just finally decided to join. I did not exactly know where to post this so bare with me if you will. Anyways, I am in my second freshman semester as an EE undergrad and I am taking Honors Physics II. As a requirement of this course I must write up a 10-page paper as well as a 5 min PowerPoint Presentation. What I wanted help with was what my topic should be about. The professor said it must be related to something we learned this year and so I would like to do something with circuitry. I am a big fan of car audio, and so I wanted to talk specifically about amps and how they function. Do you think how an amp functions would be a suitable topic for my situation? What type of theory would you suggest is related to how an amp functions in converting basic voltage into 500-1000 watts?
